Patent CA-2321902-A1 (CA)
Title: A kind of man's briefs and lining of the briefs
Inventor: QI XIAOMING
IPC: A41B9/02
Filed: 1999-06-03
Abstract: A king of man's briefs and lining of the briefs, comprising a waist section, a front section and a back section, where a support belt is connected to the front section. The bottom of the support belt has an arc shape, and forms a bag section between the bottom of the tightening position of the scrotum and the upper ends of the legs so as to facilitate supporting and holding. The two ends of the support belt flare up and are connected with the front section and the waist section to facilitate stability of the support belt and the supporting force. The support belt can be adjusted easily. By adjusting the width of the flared mouth of the support belt, the length of the support belt, or the tension of the elastic ribbon, a proper support position and a comfortable supporting force can be obtained.

Title: Telecommunications inter-exchange congestion control
Inventor: WALLENTIN PONTUS
IPC: H04M3/22
Filed: 1999-03-02
Abstract: A telecommunications network has a target exchange (RNC 2222) which determines a congestion condition in a region supervised by the target exchange, and which sends a congestion message to a source exchange (RNC 2221). The source exchange controls at least some connections which utilize radio resources in the region supervised by the target exchange. The congestion message causes the source exchange to adjust at least one connection which it controls in the region supervised by the target exchange. In a first mode of the invention, the target exchange determines a selected connection to be adjusted in view of the congestion condition. In this first mode, the congestion message identifies the selected connection to be adjusted and further includes an adjustment value (e.g., power reduction value) for the selected connection to be adjusted. In a second mode of the invention, the congestion message includes an identification of a congested area (e.g., a cell) within the region supervised by the target exchange, as well as a severity value indicating a severity of the congestion in the congested area. The severity value can be indicative of a needed decrease in congestion in the congested area.

Abstract: Aerosol ointment compositions are provided that, when a deposit is expelled from an aerosol container containing the composition onto damaged tissue, there is applied to the tissue a cold ointment which exerts a cooling pain relief effect and a medicinal therapeutic effect on the tissue. Examples of typical ointments of the invention are those for the temporary relief of hemorrhoids, treatment of sunburn and relief from arthritic pain. A method is provided for the manufacture of an aerosol ointment composition that is capable of expelling from an aerosol container an ointment that exerts on damaged tissues both a pain relieving cooling effect and a medicinal therapeutic effect. The aerosol composition enhances the therapeutic action of an ointment by instantly producing a sustained cooling effect which provides fast relief from pain and itching as well as a tendency to shrink swollen, inflamed tissue in advance of the slower action of any medication present in the ointment. The aerosol composition consists of from about 10 to about 60 percent by weight of ingredients of an ointment that is an oil-in-water emulsion and from about 40 to about 90 percent by weight of liquefied propellant that is predominantly a non-polar propellant. The sum of the ointment ingredients and the propellant equals 100 percent by weight of the composition.

Piezoceram ic dielectric allows the detector to be vibrated. The sensor can be attached to  an ultrasonic transducer. Presence of specific chemicals requires a chemical ly non-reactive and a chemically reactive electrode re the chemical of interest . If the test fluid is conductive, the changed capacitance is measured in an insulating fluid.

Inventor: HSU CHRISTOPHER
IPC: B23K9/095
Filed: 2001-10-18
Abstract: A monitor for an electric arc welder as the welder performs a selected arc welding process by creating actual welding parameters, such as arc current and arc voltage, between an advancing welding wire and a workpiece, where the process involves an arc and is defined by a series of rapidly repeating wave shapes constituting a weld cycle with a cycle time, the wave shapes are each segmented into time states having command signals corresponding to the actual parameters and a time duration. The monitor selects a specific wave shape state, reads one of the actual parameters, compares the actual read parameter with a function of the command signal corresponding to the actual parameter, and uses the comparison to generate a characteristic of the welding process during the selected state.
